The aim of this study was to develop a model to predict academic success, particularly for lower primary school level. Moving descriptive statistics, cross-tabulation and ordered logistic regression, the study found that, with respect to learner (pupil) characteristics, nursery school attendance was a significant predictor, with increased odds of academic success [OR=1.79, p=0.00]. Regarding school characteristics, studying in an urban centre, Kampala Capital City [OR=1.77, p=0.00] and the rest of urban areas [OR=2.00, p=0.00] had increased odds of a pupil’s academic success. Similarly, studying in a privately owned school [OR=4.59, p=0.00] had increased odds for a pupil’s academic success. Therefore, the study recommends that all should attend nursery school before joining formal education. Accordingly, responsible authorities should develop necessary infrastructure to promote nursery school attendance. Also, parity between rural and urban educational practice should be pursued by responsible authorities. For likely academic success, publically owned schools should be run on business model, just on the same model that privately owned schools do.
